This article introduces an incipient fault (IF) diagnosis approach for current sensors (CSs) in three-phase three-level neutral-point-clamped (3L-NPC) rectifiers using an adaptive sliding mode ...

A 130-nm CMOS high-side current sensor (CS) for peak-current dc–dc converters, operating with an input voltage up to 40 V is presented. A loop prebiasing technique is used to prevent the proposed ...
